Different types of computer systems in

According to the size and power computers are classified.
Super computers Super computers are employed for heavy usage like construction of atom bombs, weather forecasting, finding oil, earthquake predictions, electronic design and scientific simulations. These computers are extremely faster that other computers currently available. They can perform hundreds of millions of commands per second. Mainframe computers

Mainframe computers are very large, expensive and powerful multi-user computers. It supports up to hundreds of users simultaneously. It is build into a frame means all units were hung into a frame, therefore it is called mainframe computer. Banks, companies and universities use mainframe computers. Some features of this computer are given below. Has 1 to 16 CPU's

Mini computers They are low cost and midsize computers. These computers are associated with de-centralized computing that most of computing tasks place on the mini itself. A mini computer can support up to 200 users simultaneously. So it is a multi processing system. Workstations

These types of computers are used for desktop publishing, engineering applications, software development and other types of applications which required high quality graphics. UNIX and Windows NT operating systems are most commonly used in these computers. These types of computers are built in network support, contain large amount of RAM and a graphical user interface. Most workstation doesn't have a disk drive. These computers are used to form a local area network. Personal computers

Personal computers are design for an individual user. They are low-cost and small in size. These...

PCs, laptops, netbooks, PDAs, tablets & servers.
PCs
General purpose computer
This computer is designed to perform and is capable of
performing in a reasonably efficient manner, the functions
required by both scientific and business applications. Note:
A general purpose computer is often understood to be a
large system, capable of supporting remote terminal
operations, but it may also be a smaller computer, e.g., a
desktop workstation. General purpose computers are
common in all public sectors of work including schools,
small hospitals (receptionists etc.) and offices.
Laptops
The purpose of laptops is to provide users with the
capabilities of a desktop computer in an easier way by
making the system portable. However laptops generally
tend to be slower and have less graphical and sound
capabilities than a desktop PC. Family homes generally
use laptops due to their portability.
Netbooks

A netbook is a low power notebook that has less
processing power than a laptop but has a much
larger battery life. Netbooks are however able to use
word processors which makes them popular for
schools and businesses as it’s far more portable than
a standard laptop.
PDAs

...﻿Supercomputer
Supercomputer is a broad term for one of the fastest computers currently available. Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations (number crunching). For example, weather forecasting requires a supercomputer. Other uses of supercomputers scientific simulations, (animated) graphics, fluid dynamic calculations, nuclear energy research, electronic design, and analysis of geological data (e.g. in petrochemical prospecting). Perhaps the best known supercomputer manufacturer is Cray Research.
Mainframe
Mainframe was a term originally referring to the cabinet containing the central processor unit or "main frame" of a room-filling Stone Age batch machine. After the emergence of smaller "minicomputer" designs in the early 1970s, the traditional big iron machines were described as "mainframe computers" and eventually just as mainframes. Nowadays a Mainframe is a very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously. The chief difference between a supercomputer and a mainframe is that a supercomputer channels all its power into executing a few programs as fast as possible, whereas a mainframe uses its power to execute many programs concurrently. In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs. But...

Abstract
This essay is about the three types of computersystems: netbook, desktop, and laptop. They all have a different in function and purpose (they function according to what your needs are). The desktop is perfect if you are looking for a computer that is non-portable, high performance, tough and affordable. However if you are someone who want something a basic computer to surf for online information, or for a starter computer, than a netbook is right for you. However, it is not meant to download huge data or set up large applications. A laptop is an ideal choice if budget is not a major limitation, and if you want a high performance system with greater capacity and high storage. In addition, a laptop is portable. For instance you can take it to class as well as anywhere else that you need to. You have to consider these few essential factors before investing in any computersystem to benefit your needs. Therefore now that you understand the chief differences among the three computersystems: netbook, laptop, and desktop. You will be able to choose on that fits your needs.

...are a lot of terms used to describe computers. Most of these words imply the size, expected use or capability of the computer. While the term computer can apply to virtually any device that has a microprocessor in it, most people think of a computer as a device that receives input from the user through a mouse or keyboard, processes it in some fashion and displays the result on a screen.
• PC - The personal computer (PC) defines a computer designed for general use by a single person. While a Mac is a PC, most people relate the term with systems that run the Windows operating system. PCs were first known as microcomputers because they were a complete computer but built on a smaller scale than the huge systems in use by most businesses.
• Desktop - A PC that is not designed for portability. The expectation with desktop systems are that you will set the computer up in a permanent location. Most desktops offer more power, storage and versatility for less cost than their portable brethren.
• Laptop - Also called notebooks, laptops are portable computers that integrate the display, keyboard, a pointing device or trackball, processor, memory and hard drive all in a battery-operated package slightly larger than an average hardcover book.
